HAIRDRESSERS UNDULATING DEVICE.

Specification of Letters Patent.

Patented May 10, 1921.

Application filed February 24, 1921. Serial No. 447,367.

To all whom it may concern:

Be it known that l[, GOTTFRIED BEeAs, a citizen of the German Republic, residing at Berlin, Germany, have invented certain new and useful Improvements in Hairdressers Undulating Devices, of which the following is a specification.

This invention relates to undulating devices for imparting a wavy shape to hair. The object of the invention is to provide a device which is of simple construction and enables the hair to be undulated quickly without requiring much skill. This is accomplished by providing a device consisting of a single part in the shape ofa conical or tapering rod which may be furnished with the heating and guiding helix or helices winding around the rod. The helix is shaped so as to be capable of being molded and cast. To this end the parts of the helix that would form pockets in which the mold would cleave and prevent the pattern from being removed from the mold without breaking or damaging it are filled with a suitable filling. The wave-forming part of the rod consists of a longitudinal ridge or ridges running along the rod. The parts of the helix that intersect the said ridge or ridges are also provided with ridges that run outward the longitudinal ridge to the periphery of the helix.

Constructional forms of the invention are shown in the drawing in which Figure 1 is a side view of a rod shaped undulating device,

Fig. 2 is a cross section on the line AA of Fig. 1,

Fig. 3 is a cross section on the line lB-B of Fig. 1,

Fig. 4 illustrates a side view of an undulating device provided with heating and guiding rib or helix, the handle being partly broken away.

Fig. 5 represents Fig. 4 as viewed from the left,

Fig. 6 is a cross section through Fig. 4 on the line II,

Fig. 7 is across section through Fig. 4 on the line II-II, and

Fig. 8 shows a cross section through Fig. 4 on the line III-III.

The body of the undulating device conroots.

sists ofa tapering rod on the thin end of which is inserted in handle 0. As a tuft or look of hair that is to be made wavy or undulated is conical the waves formed will be of equal lengths only if the rod around which the tuft of hair is wound is also made conical. Hence the end d of the rod is made thicker thanits beginning portion 5. When the device is to be used it is first heated. Tts thin end is then held adjacent to the roots of the tuft of hair to be undulated and the tuft is thereupon wound around the rod, the thick root portion of the the tuft being thus coiled around the thin end 6 of the rod while the thin end of the tuft passes around the thick end (i of the rod.

To obtain marked and durable undulations of the hair near its roots relatively sharp ridges e are formed at the beginning portion of the rod, these ridges 6 being produced by making longitudinal furrows f in the said portion of the rod. The ridges required to produce satisfactory undulations of the thinner end portions of a tuft of hair need not be so sharp as those needed for the thick portions of the tuft near the Hence the ridges at the thick end of the rod may take the form of apexes g of an oval cross section.

The device described as shown in Figs. 1

to 3 produces well marked and uniform waves of the hair, but some minutes elapse before the necessary amount of heat is 1m parted to the hair by the surface of the rod.

In order to reduce the time required for producing eight to ten deep waves in the hair to a few seconds a heating or guiding rib or helix 2 is formed around the rod 1', a spiral channel or groove being thus produced Whose bottom and two sides form three heatin surfaces that impart heat to the hair tuft from three sides direct. In proportion to the size and density of the various parts of an average tapering tuft of hair the helix 2 is preferably thicker at the beginning 3 than at the end 4. The furrow formed by the rib or helix 2 and into which the hair is laid is largest at the beginning 5 and smallest'at the end 61' The beginning end is bound by a collar 7. As in the case of Fig. 1 the rod is thinnest at the commencement 8 where it is attached to a handle 10 and thickest at the end 9. As shown in Figs. 7 and 8 the rod may be made hollow and in such case an electric heating appliance of any suitable kind, not shown, may be inserted in the rod and connected to the electric supply mains by wires 11, 12. Longitudinal grooves 13 are made in the rod so as to form the hair-undulating ridges 17. The receding portions of the heating and guiding rib or helix 2 that would form pockets into which parts of a mold used for casting the device would enter and prevent the pattern from being extracted from the mold without breaking or damaging it, are filled out with material 14: that may be integral with the helix and rod so that the whole can be molded and cast in a two-part mold. The presence of the additional material 14 causes ridges 15, 16 to be formed that extend radially from the longitudinal ridges 17 on the rod to the periphery of the helix. The periphery 18 of the helix is uniform and of an oval shape.

The advantages obtained by the novel features of the device are (first) that the waves made in the hair are practically of equal length, (second) that very marked waves may be produced by a pulling the hair tightly around the rod, (third) that the undulations are produced very rapidly because the rod imparts heat to the hair from below and the helix heats it from the sides and indirectly from above, (fourth) that the waves produced retain their shape for a considerable time because the helix imparts a' practically equal amount of heat to each individual hair, and (fifth) that it is possible to mold and cast the undulatin device in one piece in spite of the helical shape of the rib, whereby a cheap mass production is rendered possible.
